Federal Windsor Pitcher

I am not sure which pieces of the "Windsor" pattern were made by Federal or Indiana Glass. I've never been able to get a definitive answer. This pitcher holds approximately 16 ounces and is 6 inches in height. It is the Aegean or ice blue color and is supposed to be the same shade as my other pieces, but it seems a bit more intense. Of course, this could be an optical illusion due to the structure. No damage. Photos soon.
